VIBRATOR FOR MASSAGE PURPOSES.

Specification of Letters Patent.

Patented July 9, 1907.

Application filed March 30,1905. -Serial No. 252,805.

To all whom it may concern:

Be it known that I, FREDRICK C. Asornsmmnn,` a citizen of the UnitedStates, residing at Chicago, in the county of Cookand State of Illinois,have invented certain new and useful Improvements in Vibrators forMassage Purposes, of which the following is a full, clear, and exactspecification.

My invention relates gto massage instruments or vi-4 brators of thatcharacter designed to produce mechanical vibration of the part of fleshor body to be treated, and it has for its object to provide an improvedand efficient form of vibrator which may be readily convorted from atapping into a rubbing or smoothing form of instrument.

With a view to the attainment of these ends and the accomplishment ofcertain other objects which will hereinafter appear, the inventionconsists in certain features of novelty in the construction, combinationand arrangement of parts which will now be described with reference tothe accompanying drawings and more particularly pointed out in theclaims.

In the said drawings- Figure 1 is an end view of my improved instrument.Fig. 2 is a similarv view with the cover removed and certain parts insection. Fig. i3 is a longitudinal section on the line 3, 3 Fig. 2, andFig. 4 is a View looking from the left in Fig. 2 with the top portion insection on the line 4, 4 Fig. 2.

1 is a cross head or other suitable reciprocating member contained inany suitable guide 2 and to the outer end of this cross head is secureda stem 3 on which is pivotally mounted a massage button or knob 4adapted to be applied to the surface to be treated. The means ofattachment of the knob 4 to the stem 3 is a hinge 5 whereby the knob maybe arranged in line with the stem 3 and the direct line of movement ofthe cross head 1 and in which position the knob will produce a tappingmovement upon the surface to be treated, corresponding in degree ofvibration to the length and rapidity of stroke of the cross head l; orif desired the knob 4 maybe turned on a hinge 5, as shown in dottedlines in Fig. 3, whereby it will be at an angle to the line of movementof the cross head l and may be utilized for producing a rubbing orstroking action on the surface to be treated, the hinge 5 beingsufficiently tight to hold the knob 4 in its various positions duringuse.

The cross head l derives reciprocal movement in the guide 2 from anysuitable source of pwer transmitted to the cross head 1 in any suitableway, and in the exemplification of the invention shown in the drawingsthe source of power is supposed to be a distant motor not necessary toillustrate, transmitting its motion to the apparatus through theintermediary of a iiexible shaft G, and this in turn is connected bysuitable means to the cross head 1. The guide 2 is preferably formed ona ring 7, which constitutes a part of the casing for housing themechanism, and into the bottom of this ring is screwed a bearing plate 8formed with a ball race 9 in 'which are situated antifriction rollers orballs 10 supporting a cup shaped cam 1l which has an oval shapedinterior 12, as better' shown in Fig. 2, and in which engages anantifriction roller 13 pinned to a lever 14 so that when the cam l-l isrotated the lever 14 will be accordinglyoscillated, the roller 13 beingmaintained against the wall 12 by any suitable spring l5 coiled aroundthe pivot 16 which supports the lever 14 from a cap or cover 17 securedin the ring 7. The lever 14 is connected to the cross head 1 by means ofa pitman 18 so that as the lever oscillates the cross head will bereciprocated.

In order that the length of stroke of the cross head may be varied tosuit different requirements, the point of connection between the pitman18 and the lever 14 is shiftable and to that end the lever is providedwith a slot 19 in which engages a pin or stud 20 that serves as themeans of attachment between the pitman and the lever, and this stud 20is connected to an operating handle 2l arranged on the exterior of thecover 17 and secured thereto by a short shaft 22 which passes throughthe cover and is rigidly connected to an arm 23 within the casing, andthis arm in turn is connected by a hinged elbow 24 to the stud 2O sothat when the lever 2l is oscillated the stud 20 will be forced back andforth in the slot 19 thereby varying the length of stroke of the crosshead 1. The cam 11 is connected to the flexible shaft 6 by a shaft 25which extends downwardly through a neck 26 on the bearing plate 8 and isscrewed or' otherwise secured to a journal 27, between which andaninternal flange 28 in the neck 26, are interposed a number ofantifriction balls or rollers 29, thus constituting an end thrustbearing for holding the cam 1l in placeon the bearing plate 8 and at thesame time affording an antifriction bearing for the 'flexible shaft 6,which is secured to the end of the journal 27 and is inclosed by ahollow handle 30 secured on the neck 26.

Having thus described my invention, what I claim as new therein anddesire to secure by Letters Patent,

1A In an apparatus for the purpose described the combination of anangularly adjustable applicator', a reciprocal cross head to which saidapplicator is connected, means for reciprocating said cross head, andmeans intermediate tlie cross head and the reciprocating means forvaryingr the length of the stroke of said cross head.

2. In an apparatus for the purpose described the combination of anapplicator, a reciprocal member for vlbratinf.; said applicator, apivoted lever operatively connected with said member for reciprocatingit, and means for shifting the point of connection between said leverand its operative connection with said member whereby the length ofstroke of said member will be varied.

3. In an apparatus for the purpose described the combination of anapplicator, a pitman operatively connected therewith, a slotted lever, astud secured to said pitman i and arranged in said slot, means forvibrating said lever,

and means for shifting said stud.

-L 1n an apparatus for the purpose described the combination of anapplicator, a casing, means within said casing operatively connectedwith said applicator for vibrating it, said means comprising two pivotedmembers adjustably connected, a pivoted lever on the exterior of thecasing, connected with one of said interior members to shift the samefor varyingr the length of stroke of the applicator.

5. In an apparatus for the purpose described the combination of anapplicator, a stem to which said applicator -is hinged, a casing havinga guide for .said stem, a lever pivoted in said casing, a pitmanconnected with said lever and said stem, a cam journaled in said casing,a neck projecting from said casing, a shaft secured to said cam andjournaled in said neck, a handle inclosing,I said shaft, and meansprojecting into said handle for rotating saidshaft.

6. In an apparatus for the purpose described, the combination of anapplicator, a casing, a pivoted lever Within the casing, a connectionpivoted to the applicator and adjustably engaging the lever, means forrocking the lever to vibrate the applicator, and means located on theoutside of the casing and operatively related to the point ot'engagement of the connection with the lever, for shifting said point tovary the stroke of the applicator.
